Method and apparatus for classifying a mobile device location

摘要

Methods, apparatus, and computer program products for classifying a mobile device location are described. An example of a method for classifying the mobile device location includes mapping the mobile device location to a pixel address in a dilated test texture, wherein the dilated test texture corresponds to an uncertainty estimation associated with the mobile device location and determining an in-out classification of the mobile device location based on a query of a pixel value associated with the pixel address in the dilated test texture.

主权项

1. A method of classifying a mobile device location implemented by one or more processors, a graphics processing unit (GPU), or a combination thereof comprising:
storing, by the one or more processors, the GPU, or the combination thereof, a dilated test texture in a GPU frame buffer, the dilated test texture being rasterized mapping information morphologically dilated according to a morphological dilation operation based on an uncertainty estimation associated with the mobile device location; mapping, by the one or more processors, the GPU, or the combination thereof the mobile device location to a particular pixel address in the GPU frame buffer associated with the dilated test texture; determining, by the one or more processors, the GPU, or the combination thereof, an in-out classification of the mobile device location based on a query of a pixel value associated with the particular pixel address in the GPU frame buffer associated with the dilated test texture; and outputting, by the one or more processors, the GPU, or the combination thereof, the in-out classification of the mobile device location.
